DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

Referring initially to FIG. 1, an exemplary embodiment of an expandable tubular assembly 10 includes a first expandable tubular member 12 coupled to a second expandable tubular member 14. In several exemplary embodiments, the ends of the first and second expandable tubular members, 12 and 14, are coupled using, for example, a conventional mechanical coupling, a welded connection, a brazed connection, a threaded connection, and/or an interference fit connection. In an exemplary embodiment, the first expandable tubular member 12 has a plastic yield point YP₁, and the second expandable tubular member 14 has a plastic yield point YP₂. In an exemplary embodiment, the expandable tubular assembly 10 is positioned within a preexisting structure such as, for example, a wellbore 16 that traverses a subterranean formation 18.

As illustrated in FIG. 2, an expansion device 20 may then be positioned within the second expandable tubular member 14. In several exemplary embodiments, the expansion device 20 may include, for example, one or more of the following conventional expansion devices: a) an expansion cone; b) a rotary expansion device; c) a hydroforming expansion device; d) an impulsive force expansion device; d) any one of the expansion devices commercially available from, or disclosed in any of the published patent applications or issued patents, of Weatherford International, Baker Hughes, Halliburton Energy Services, Shell Oil Co., Schlumberger, and/or Enventure Global Technology L.L.C. In several exemplary embodiments, the expansion device 20 is positioned within the second expandable tubular member 14 before, during, or after the placement of the expandable tubular assembly 10 within the preexisting structure 16.

As illustrated in FIG. 3, the expansion device 20 may then be operated to radially expand and plastically deform at least a portion of the second expandable tubular member 14 to form a bell-shaped section.

As illustrated in FIG. 4, the expansion device 20 may then be operated to radially expand and plastically deform the remaining portion of the second expandable tubular member 14 and at least a portion of the first expandable tubular member 12.

In an exemplary embodiment, at least a portion of at least a portion of at least one of the first and second expandable tubular members, 12 and 14, are radially expanded into intimate contact with the interior surface of the preexisting structure 16.

In an exemplary embodiment, as illustrated in FIG. 5, the plastic yield point YP₁ is greater than the plastic yield point YP₂. In this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand the second expandable tubular member 14 is less than the amount of power and/or energy required to radially expand the first expandable tubular member 12.

In an exemplary embodiment, as illustrated in FIG. 6, the first expandable tubular member 12 and/or the second expandable tubular member 14 have a ductility D_(PE) and a yield strength YS_(PE) prior to radial expansion and plastic deformation, and a ductility D_(AE) and a yield strength YS_(AE) after radial expansion and plastic deformation. In an exemplary embodiment, D_(PE) is greater than D_(AE), and YS_(AE) is greater than YS_(PE). In this manner, the first expandable tubular member 12 and/or the second expandable tubular member 14 are transformed during the radial expansion and plastic deformation process. Furthermore, in this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand each unit length of the first and/or second expandable tubular members, 12 and 14, is reduced. Furthermore, because the YS_(AE) is greater than YS_(PE), the collapse strength of the first expandable tubular member 12 and/or the second expandable tubular member 14 is increased after the radial expansion and plastic deformation process.

In an exemplary embodiment, as illustrated in FIG. 7, following the completion of the radial expansion and plastic deformation of the expandable tubular assembly 10 described above with reference to FIGS. 1-4, at least a portion of the second expandable tubular member 14 has an inside diameter that is greater than at least the inside diameter of the first expandable tubular member 12. In this manner a bell-shaped section is formed using at least a portion of the second expandable tubular member 14. Another expandable tubular assembly 22 that includes a first expandable tubular member 24 and a second expandable tubular member 26 may then be positioned in overlapping relation to the first expandable tubular assembly 10 and radially expanded and plastically deformed using the methods described above with reference to FIGS. 1-4. Furthermore, following the completion of the radial expansion and plastic deformation of the expandable tubular assembly 20, in an exemplary embodiment, at least a portion of the second expandable tubular member 26 has an inside diameter that is greater than at least the inside diameter of the first expandable tubular member 24. In this manner a bell-shaped section is formed using at least a portion of the second expandable tubular member 26. Furthermore, in this manner, a mono-diameter tubular assembly is formed that defines an internal passage 28 having a substantially constant cross-sectional area and/or inside diameter.

Referring to FIG. 8, an exemplary embodiment of an expandable tubular assembly 100 includes a first expandable tubular member 102 coupled to a tubular coupling 104. The tubular coupling 104 is coupled to a tubular coupling 106. The tubular coupling 106 is coupled to a second expandable tubular member 108. In several exemplary embodiments, the tubular couplings, 104 and 106, provide a tubular coupling assembly for coupling the first and second expandable tubular members, 102 and 108, together that may include, for example, a conventional mechanical coupling, a welded connection, a brazed connection, a threaded connection, and/or an interference fit connection. In an exemplary embodiment, the first and second expandable tubular members 12 have a plastic yield point YP₁, and the tubular couplings, 104 and 106, have a plastic yield point YP₂. In an exemplary embodiment, the expandable tubular assembly 100 is positioned within a preexisting structure such as, for example, a wellbore 110 that traverses a subterranean formation 112.

As illustrated in FIG. 9, an expansion device 114 may then be positioned within the second expandable tubular member 108. In several exemplary embodiments, the expansion device 114 may include, for example, one or more of the following conventional expansion devices: a) an expansion cone; b) a rotary expansion device; c) a hydroforming expansion device; d) an impulsive force expansion device; d) any one of the expansion devices commercially available from, or disclosed in any of the published patent applications or issued patents, of Weatherford International, Baker Hughes, Halliburton Energy Services, Shell Oil Co., Schlumberger, and/or Enventure Global Technology L.L.C. In several exemplary embodiments, the expansion device 114 is positioned within the second expandable tubular member 108 before, during, or after the placement of the expandable tubular assembly 100 within the preexisting structure 110.

As illustrated in FIG. 10, the expansion device 114 may then be operated to radially expand and plastically deform at least a portion of the second expandable tubular member 108 to form a bell-shaped section.

As illustrated in FIG. 11, the expansion device 114 may then be operated to radially expand and plastically deform the remaining portion of the second expandable tubular member 108, the tubular couplings, 104 and 106, and at least a portion of the first expandable tubular member 102.

In an exemplary embodiment, at least a portion of at least a portion of at least one of the first and second expandable tubular members, 102 and 108, are radially expanded into intimate contact with the interior surface of the preexisting structure 110.

In an exemplary embodiment, as illustrated in FIG. 12, the plastic yield point YP₁ is less than the plastic yield point YP₂. In this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand each unit length of the first and second expandable tubular members, 102 and 108, is less than the amount of power and/or energy required to radially expand each unit length of the tubular couplings, 104 and 106.

In an exemplary embodiment, as illustrated in FIG. 13, the first expandable tubular member 12 and/or the second expandable tubular member 14 have a ductility D_(PE) and a yield strength YS_(PE) prior to radial expansion and plastic deformation, and a ductility D_(AE) and a yield strength YS_(AE) after radial expansion and plastic deformation. In an exemplary embodiment, D_(PE) is greater than D_(AE), and YS_(AE) is greater than YS_(PE). In this manner, the first expandable tubular member 12 and/or the second expandable tubular member 14 are transformed during the radial expansion and plastic deformation process. Furthermore, in this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand each unit length of the first and/or second expandable tubular members, 12 and 14, is reduced. Furthermore, because the YS_(AE) is greater than YS_(PE), the collapse strength of the first expandable tubular member 12 and/or the second expandable tubular member 14 is increased after the radial expansion and plastic deformation process.

Referring to FIG. 14, an exemplary embodiment of an expandable tubular assembly 200 includes a first expandable tubular member 202 coupled to a second expandable tubular member 204 that defines radial openings 204 a, 204 b, 204 c, and 204 d. In several exemplary embodiments, the ends of the first and second expandable tubular members, 202 and 204, are coupled using, for example, a conventional mechanical coupling, a welded connection, a brazed connection, a threaded connection, and/or an interference fit connection. In an exemplary embodiment, one or more of the radial openings, 204 a, 204 b, 204 c, and 204 d, have circular, oval, square, and/or irregular cross sections and/or include portions that extend to and interrupt either end of the second expandable tubular member 204. In an exemplary embodiment, the expandable tubular assembly 200 is positioned within a preexisting structure such as, for example, a wellbore 206 that traverses a subterranean formation 208.

As illustrated in FIG. 15, an expansion device 210 may then be positioned within the second expandable tubular member 204. In several exemplary embodiments, the expansion device 210 may include, for example, one or more of the following conventional expansion devices: a) an expansion cone; b) a rotary expansion device; c) a hydroforming expansion device; d) an impulsive force expansion device; d) any one of the expansion devices commercially available from, or disclosed in any of the published patent applications or issued patents, of Weatherford International, Baker Hughes, Halliburton Energy Services, Shell Oil Co., Schlumberger, and/or Enventure Global Technology L.L.C. In several exemplary embodiments, the expansion device 210 is positioned within the second expandable tubular member 204 before, during, or after the placement of the expandable tubular assembly 200 within the preexisting structure 206.

As illustrated in FIG. 16, the expansion device 210 may then be operated to radially expand and plastically deform at least a portion of the second expandable tubular member 204 to form a bell-shaped section.

As illustrated in FIG. 16, the expansion device 20 may then be operated to radially expand and plastically deform the remaining portion of the second expandable tubular member 204 and at least a portion of the first expandable tubular member 202.

In an exemplary embodiment, the anisotropy ratio AR for the first and second expandable tubular members is defined by the following equation:

AR=ln(WT _(f) /WT _(o))/ln(D _(f) /D _(o));

where AR=anisotropy ratio;

where WT_(f)=final wall thickness of the expandable tubular member following the radial expansion and plastic deformation of the expandable tubular member;

where WT_(i)=initial wall thickness of the expandable tubular member prior to the radial expansion and plastic deformation of the expandable tubular member;

where D_(f)=final inside diameter of the expandable tubular member following the radial expansion and plastic deformation of the expandable tubular member; and

where D_(i)=initial inside diameter of the expandable tubular member prior to the radial expansion and plastic deformation of the expandable tubular member.

In an exemplary embodiment, the anisotropy ratio AR for the first and/or second expandable tubular members, 204 and 204, is greater than 1.

In an exemplary experimental embodiment, the second expandable tubular member 204 had an anisotropy ratio AR greater than 1, and the radial expansion and plastic deformation of the second expandable tubular member did not result in any of the openings, 204 a, 204 b, 204 c, and 204 d, splitting or otherwise fracturing the remaining portions of the second expandable tubular member. This was an unexpected result.

Referring to FIG. 18, in an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 are processed using a method 300 in which a tubular member in an initial state is thermo-mechanically processed in step 302. In an exemplary embodiment, the thermo-mechanical processing 302 includes one or more heat treating and/or mechanical forming processes. As a result, of the thermo-mechanical processing 302, the tubular member is transformed to an intermediate state. The tubular member is then further thermo-mechanically processed in step 304. In an exemplary embodiment, the thermo-mechanical processing 304 includes one or more heat treating and/or mechanical forming processes. As a result, of the thermo-mechanical processing 304, the tubular member is transformed to a final state.

In an exemplary embodiment, as illustrated in FIG. 19, during the operation of the method 300, the tubular member has a ductility D_(PE) and a yield strength YS_(PE) prior to the final thermo-mechanical processing in step 304, and a ductility D_(AE) and a yield strength YS_(AE) after final thermo-mechanical processing. In an exemplary embodiment, D_(PE) is greater than D_(AE), and YS_(AE) is greater than YS_(PE). In this manner, the amount of energy and/or power required to transform the tubular member, using mechanical forming processes, during the final thermo-mechanical processing in step 304 is reduced. Furthermore, in this manner, because the YS_(AE) is greater than YS_(PE), the collapse strength of the tubular member is increased after the final thermo-mechanical processing in step 304.

In an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, have the following characteristics:

Characteristic Value Tensile Strength 60 to 120 ksi Yield Strength 50 to 100 ksi Y/T Ratio Maximum of 50/85% Elongation During Radial Expansion and Minimum of 35% Plastic Deformation Width Reduction During Radial Expansion Minimum of 40% and Plastic Deformation Wall Thickness Reduction During Radial Minimum of 30% Expansion and Plastic Deformation Anisotropy Minimum of 1.5 Minimum Absorbed Energy at −4 F. (−20 C.) 80 ft-lb in the Longitudinal Direction Minimum Absorbed Energy at −4 F. (−20 C.) 60 ft-lb in the Transverse Direction Minimum Absorbed Energy at −4 F. (−20 C.) 60 ft-lb Transverse To A Weld Area Flare Expansion Testing Minimum of 75% Without A Failure Increase in Yield Strength Due To Radial Greater than 5.4% Expansion and Plastic Deformation

In an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, are characterized by an expandability coefficient f:

i. f=r×n

ii. where f=expandability coefficient;

-   -   1. r=anisotropy coefficient; and     -   2. n=strain hardening exponent.

In an exemplary embodiment, the anisotropy coefficient for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is greater than 1. In an exemplary embodiment, the strain hardening exponent for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is greater than 0.12. In an exemplary embodiment, the expandability coefficient for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is greater than 0.12.

In an exemplary embodiment, a tubular member having a higher expandability coefficient requires less power and/or energy to radially expand and plastically deform each unit length than a tubular member having a lower expandability coefficient. In an exemplary embodiment, a tubular member having a higher expandability coefficient requires less power and/or energy per unit length to radially expand and plastically deform than a tubular member having a lower expandability coefficient.

In several exemplary experimental embodiments, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, are steel alloys having one of the following compositions:

If the user selects expansion in step 4402, then the controller 4338 determines if the operating pressure of the accumulator 4310, as sensed by the pressure sensor 4342, is greater than or equal to a predetermined value in step 4404.

If the operating pressure of the accumulator 4310, as sensed by the pressure sensor 4342, is not greater than or equal to the predetermined value in step 4404, then the controller 4338 operates the pump 4328 to increase the operating pressure of the accumulator in step 4406. The controller 4338 then determines if the operating pressure of the accumulator 4310, as sensed by the pressure sensor 4342, is greater than or equal to a predetermined value in step 4408. If the operating pressure of the accumulator 4310, as sensed by the pressure sensor 4342, in step 4408, is not greater than or equal to the predetermined value, then the controller 4338 continues to operate the pump 4328 to increase the operating pressure of the accumulator in step 4406.

If the operating pressure of the accumulator 4310, as sensed by the pressure sensor 4342, in steps 4404 or 4408, is greater than or equal to the predetermined value, then the controller 4338 operates the flow control valve 4306 to pressurize the expansion element 4302 in step 4410 by positioning the flow control valve to couple the flow lines 4304 and 4308 to one another. If the expansion operation has been completed in step 4412, then the controller 4338 operates the flow control valve 4306 to de-pressurize the expansion element 4302 in step 4414 by positioning the flow control valve to couple the flow lines 4304 and 4312 to one another.

In several exemplary embodiments, one or more of the hydroforming expansion devices 4002, 4104, and 4202, incorporate one or more elements of the hydroforming expansion system 4300 and/or the operational steps of the method 4400.
